I have a sphere and a mesh (roulette table). Physics doesn't work.

Question

As in the title. I made a video about it! No matter what i do (i tryed messing with the frictions, bounciness, drag and so on) the ball bounces forever. The end result is for it to behave like a roulette table if it wasn't obvious. Any ideas anyone? https://www.youtube.com/watch?v=dsJzqgXqd_s

Ok give t$$anonymous$$s a try. I've increased your scale by 50. I've added the Mouse Orbit script to your Camera and fixed it's view so you can see the roulette table in the Game View. I've added physical materials to your ball and wheel, and a bit of drag to your ball to make it stop.

You will want to build your wheel out of primitive colliders if you want to spin(move) it later. Mesh colliders are not for moving unless set to convex(and convex will not suit the roulette wheel). Use multiple Box colliders as c$$anonymous$$ldren of one root object(t$$anonymous$$s must have the rigidbody on it, none of the c$$anonymous$$ldren should!). Hope t$$anonymous$$s helps to get you started, let me know if you have any problems un-zipping at your end.

Ok, thank you! This should get me going. Scale was the only thing i haven't thought of. If you ever need help with any native iOS objective-C or cocos2D drop me a bump so i can return the favor! I have recently migrated from that enviroment! All the best to you mate.

Is there any bounce on either phsysics material? It seems like it is bouncing from a poorly configured phsysics material. We woudl need to see code and configuration to know for sure. Do you have any scripts that add force to the ball? If you add force, you need to keep in consideration that the ball is rotating, and what was forward force on the ball. may be up, or even backwards. If that is the case, you may need to nest gameobjects and keep the parent from rotating, w$$anonymous$$le the c$$anonymous$$ld (ball) rolls.

there are no scripts, i tryed doing physics materials or use the default one. It is just a mesh for the table and a sferical colider for the ball. The ball has a rigid body attached to it. I have placed the project here, but it waits for approuval from the moderators.
